We hope you find Linux4Win a convenient way to begin learning and using Linux.
And if you ever need to uninstall Linux4Win, just use the "uninstall.bat" script located in the "lnx4win" folder on your hard drive. Then delete the entire folder to remove it completely.
To remove the GRUB boot-loader from your machine, boot from a Windows startup disk and run the command "fdisk /mbr" on the hard drive that contains the master boot record.
